MACHINE FOR FINISHING VELVETS AND OTHER PlLE FABRICS.

SPECIFICATION forming part of Letters Patent No. 474,396, dated May 10,1892.

Application filed January 25, 1892. Serial No. 419,127. (No model.)

To all whom it may concern:

Be it known that we, EDWIN T. MARBLE and EDWIN I-I. MARBLE, bothcitizens of the United States, residing at \Vorcester, in the county ofWorcester and State of Massachusetts, have invented new and usefulImprovements in Machines for Finishing Velvets, Velveteens, Plushes, andother Pile Fabrics, of which the following, together with theaccompanying drawings, is a specification sufficlently full, clear, andexact to enable persons skilled in the art to which this inventionappertains to make and use the same.

Our present invention relates to improvements in the construction andarrangement of certain parts of the mechanism in that class of machinesemployed for performing upon cut pile fabrics the operation calledpegging the surface or pile; and it consists in the novel features ofconstruction and arran gement of devices as hereinafter explained, andparticularly defined in the summary.

The object of our invention is to render the machines more efficient anddesirable and to avoid certain objections incident to machines of thisclass as heretofore constructed.

In the drawings, Figure 1 is a side view of a machine, illustrating ourinvention. Fig. 2 is a plan view of the same. Fig. 3 isa part side andpart sectional view, on a somewhat larger scale, showing the improvedguides and pressure mechanism. Fig. 4 is avertical section through thetable, peg-bar, and guide-rolls. Fig. 5 shows the detail of theswing-stops and equipoise devices. Fig. 6 shows the detail of thehandle-bar and stop for gaging and sustaining the peg-bar at positiveworking position in its upward stroke. Fig. 7 shows the pegbar end asmade with eccentric journals.

It will be understood that in general nature and operation our machineis in some respects similar to those now in use, (see English PatentsNo.11,25l, of 1846, and No.1,823, of 1860,) and all parts other than theimprovements herein specified can be made substantially as heretoforepracticed or in any suitable .wellknown form.

Referring to parts, A denotes the frame; B,

. the peg-bar carrying the peg b; C, the slidebearings in which thepeg-bar journals 0 are mounted; D, the top guides, and d the underguides, between which said slide-bearings work.

F indicates the table or pegging-slab for supporting the fabric; E, theconnecting-rods for moving the peg-bar; G, the vibrating levers, workedby connections G and cranks H on the operating-shaft H, wherebyreciprocative action is imparted to the connections E and peg-bar in theusual manner. Afeedroll I and a tension-roll J, both covered withcard-clothing, are provided for advancing and straining the fabric inwell-known manner, and guide-rolls I and J are disposed at front andrear of the table,below the level thereof, for retaining the fabricclose and taut upon the surface of the table as it passes over the sameon its way from the place of entrance to the place of delivery. Thecourse of the fabric is indicated by the dot-and-dash line W on thedrawings.

The table or pegging-slab F is rigidly fixed in the frame, and its topis shaped with a fiat working surface, which extends over the greaterportion thereof, while its rear edge at f is downwardly curved in thepeculiar manner shown, the said curved surface approaching and merginginto the fiat surface by a smooth and gradually-diminishing convexity,the lines of the surface being straight transversely of the machine.

The guides D and d are made with straightline faces and of such lengththat the slide bearings or boxes 0 in which the peg-bar is mounted canmove therein far enough to carry the peg-bar beyond the limits of thetable F at both front and rear, so that said peg-bar will pass the edgef and be entirely free from the table when the oscillative action of thebar for bringing the peg to upright position is effected. The lowerguides cl are adjustably secured to the cheek-pieces A of the frame bymeans of bolts 3, and setting-screws 4 are provided, fitted inprojections a, fixed on the cheeks, for effecting accurate adjustment ofsaid guides in relation to the table-surface. These adjustable guides clserve to limit the approach of the peg-bar to the table-surface, so thatwhateverpressure is put upon the mechanism the pegcannot take bearingsufficient to destroy-the fabric operated upon; also, to slightly varythe line of peg-action in relation to the plane of the table-surface.The yielding top guides, against which the boxes 0 slide and by whichthe peg -'bar is pressed down to the fabric, are made straightthroughout their guiding-surface, so that the peg-bar will move in adirect line from one limit of its action to the other, except whatslight deviation maybe due to its yielding, and for controlling thepressure and yield of said guide we combine with the end of eachguide-bar D a spring S, disposed within a socket or case K, fixed on theframe A. An adjusting-screw L, having a shouldered head Z, on which thespring S is seated, extends up through the coil of the spring andthrough an opening in the bar D, and a hand-wheel nut M and check-nut mare fitted upon the threaded end of said screw in themanner-illustrated,

whereby the tension of the spring can be readily adjusted by theoperator to give the required degree of pressure for hearing the peg bfirmly upon the work. This arrangement of spring and its adjustingdevices affords a more desirable and efficient pressure for the peg-bar,avoids the noise and jumping action, and is more conveniently andperfectly adjustable than the weight devices heretofore employed in thisclass of machines. The upper end of the guide D may be hinged to thevertically-adjustable bracket D in the usual manner or otherwisesuitably attached.

A stop-guard 6 is adjustably attached to the exterior of thespring-containin g socket K and provided with a set-screw 7, which guardprevents the spring from drawing the yielding guide-bar D downsuiiiciently close to the guide-bar cl to cramp the sliding box 0between them.

By making the guides D for the sliding boxes 0 straight throughouttheirlength and the table or slab F with the downwardlycurved edgefa'ndmoving the peg-bar past the edge of the table or slab F, the noise andwear of the mechanism are greatly reduced, a more efficient and rapidaction can be effected, and the parts can be easily adjusted or repairedwhen the surfaces become worn, so that with our improvements it ispractical to operate the machine with nearly double the speed andefficiency of former machines.

The handle-bar N, which is fixed to the pe bar axle c, we make anextension or lug n, and provide a stop or stud 5, attached to thesliding box 0, against which stud said lug 91. engages for arresting thedownward oscillative movement of the bar B when the peg b is at properworking position and for causing said peg-bar to positively stand at agiven fixed angle relatively to the table-surfaceduring the peggingstroke or while the peg is moving upward along the incline of the tablein contact with the pile of the fabric.

The peg bar axles or journals extend through the sliding boxes 0 andalso through the bearings e at the ends of the connectingrodsE, and saidaxles are preferably made with the journal 0 for the box-bearing and thej our= nal c for the connecting-rod bearing 6 slightly eccentric to eachother, (see Fig. 7,) the axis of the journal 0 being above the axisc, sothat the force applied through the connectingrods E for moving thepeg-bar will tend to give to said peg-bar an oscillative movement ateach end of its stroke as the direction of its motion is changed,swinging the peg downward for the working stroke and upward for thereturn stroke. The peg-baris disposed so that its weight is below oroutof line with the axis of its supporting-journal c, and the weightthus disposed tends to throw the bar over or oscillate it at the changeof direction of the reciprocative movement when made without theeccentric axles above described.

To prevent the peg-bar becoming inverted or thrown over too far on itsreturn stroke we provide an arm P, which is fixed upon the end oftheaxle c and furnished with an offset or stud 1', that projects under theconnecting-bar bearing e and engages therewith (or with a stop formed onthe bearing-box C, if preferred) when the peg-bar swings upward,limiting its movement vto a normal degree, suitable for its clearance ofthe fabric at the return stroke.

In connection with the peg-bar and preferably on the arm P we provide asuitable supporter and an adjustable weight R, that serves as an equipoise for the oscillative tendency of the peg-bar, and by means ofwhich, by adjusting said weight farther from or nearer to the axis, theoscillative force rcsultant from change in direction of motion of thebar can be regulated or modified to accommodate any speed at which themachine may be run.

In the operation the fabric passes through the machine on the lineindicated, and on its way from the tension-roll J to the feed-roll I iscarried beneath the rolls J and I, that keep the fabric smooth, and isadvanced by the feed over the surface of the slab or table F, which isbetween said rolls, with a constant movement. The bar B, carrying thepeg b, is moved over the surface of the table and its curved edge f in adirect line and is pressed down by the guides D, acted on by the springsS. The bar is oscillated at positions beyond the edges of the table, sothat the peg b is approximately horizontal on its downstroke and uprighton its upstroke, and the working edge of the peg approaches and meetsthe fabric on the gradually-curved edge surfaces f, thereby avoidingshock or strain on the pile when it strikes the fabric. The work ofpegging is performed in a thorough and expeditious manner by the passingof the peg over the pile in successive strokes.

It willbe understood that we do not broadly claim the general featuresin a machine for the purpose specified of employing a table and movablebar-peg for finishing cut pile fabrics, as such features are not of ourinvention, but

that our invention includesZthe particular features of improvement instructure, arrangement, and operation illustrated and defined.
